A portable motor chain saw comprises a machine body ( 1 ) which a driving unit, a rear handle ( 2 ), a front handle which extends over the machine body, a guide bar ( 6 ), and a dog device ( 15 ) provided such that it can be pressed against the object to be worked by means of the machine, said dog device forming a center of rotation for turning the guide bar in the plane of the guide bar. The characterising features are that the dog member ( 15 ) is provided in front of the front handle ( 3 ), approximately on a level with that part ( 4 ) of the front handle which extends over the machine body, and is connected to the front handle, and that at least that part of the dog device which is provided to engage the object to be worked, consists of a polymeric material. Preferably, the height of the dog device over the guide bar corresponds to two to three times the vertical width of the guide bar. |
